目的 比较超声、CT检查在肾肿 瘤临床诊断中应用价值。方法 选择我 院2013年1月-2014年12月期间收治72例 肾肿瘤住院患者进行研究，均行超声检 查与CT检查，明确两种检查影像学特点 并比较诊断准确性。结果 超声诊断准 确率为88.9%(64/72)，CT诊断准确率为 90.3%(65/72)，两种检查方法准确率的 比较无统计学意义(P＞0.05)。结论 可 将超声作为肾肿瘤首选检查方法以明确 肿瘤大小、位置、来源等情况及对周围 组织侵蚀情况，当肿瘤边界不清、无法 确定周围组织浸润及肾静脉癌栓形成情 况时可联合CT检查提高诊断符合率，为 手术及预后的改善提供指导。

Objective To compare the application value of ultrasonography and CT in the clinical diagnosis of renal tumors. Methods 72 cases of inpatients with renal tumors admitted into the hospital from January 2013 to December 2014 were studied and were examined by ultrasonography and CT examination to make the imaging characteristics of the two examinations clear and to compare the diagnostic accuracy. Results The accuracy rate of ultrasonic diagnosis was 88.9% (64/72) while of CT was 90.3% (65/72) and the difference was not statistically significant (P>0.05). Conclusion Ultrasonography can be taken as the preferred inspection method for renal tumors to make their size, location, source and the erosion of the surrounding tissue clear. When the tumor boundary is not clear and the surrounding tissue infiltration and renal vein tumor thrombus formation cannot be determined, it can be combined with CT examination to improve the coincidence rate of diagnosis and to provide guidance for the improvement of operation and the prognosis.
